Is Kratom Legal in Wisconsin?

No. Kratom is illegal in Wisconsin. The state classifies Kratom and its alkaloids (mitragynine and 7-Hydroxymitragynine) as controlled substances, making it illegal to buy, sell, or possess Kratom within the state.

Wisconsin Kratom Law: 2026 Legal Status Summary

Before exploring Wisconsin’s Kratom laws in detail, this quick overview highlights the state’s current legal status, restrictions, and key regulations:

Wisconsin Kratom Law Timeline

Wisconsin's position on Kratom has remained largely unchanged for more than a decade. Understanding the key legislative developments helps explain why Kratom remains prohibited in the state today.

2014 State Action

Wisconsin became one of the earliest states to prohibit Kratom-related alkaloids through state legislation.

• The process began with Senate Bill 325 (SB 325), introduced in 2013 and signed into law in 2014.
• The legislation added mitragynine and 7-Hydroxymitragynine to Wisconsin's Schedule I controlled substances list.

As a result, Wisconsin established a statewide prohibition that is still in place today.

⭐Key Developments

Although Wisconsin's prohibition has remained in place, several efforts have been made to revisit the state's approach:

• Assembly Bill 599 (2017) proposed replacing the prohibition with a regulated framework.
• Assembly Bill 393 (2023) introduced another Kratom Consumer Protection Act (KCPA)-style proposal. The bill sought to establish product standards, labeling requirements, and regulatory oversight instead of a statewide ban.

Despite these proposals, no legislation has successfully changed Wisconsin's existing Schedule I classification.

Current Status in 2026

As of 2026:

• ✔️ Kratom remains prohibited throughout Wisconsin.
• ✔️ Mitragynine remains listed as a Schedule I controlled substance under state law.
• ✔️ 7-Hydroxymitragynine remains listed as a Schedule I controlled substance under state law.
• ✔️ No bill has been enacted to replace Wisconsin's current prohibition with a regulatory framework.

Why Is Kratom Illegal in Wisconsin?

Wisconsin’s current position on Kratom comes from the way the state’s controlled substance laws are structured. Let’s take you through the legal framework behind the prohibition and the specific factors that shaped Wisconsin’s approach.

Wisconsin's Controlled Substance Classification

Kratom's alkaloids sit within Wisconsin Statute 961.14, the same statute that lists Schedule I substances such as heroin and LSD.

Which Kratom Alkaloids Are Listed Under State Law?

Two specific compounds are named in the statute:

• Mitragynine
• 7-Hydroxymitragynine

Both are listed regardless of the concentration found in a given product, meaning whole-leaf Kratom is covered along with any concentrated form.

The Legal Basis Behind Wisconsin's Prohibition

Wisconsin lawmakers added Kratom-related alkaloids to the Schedule I list in 2014 as part of a broader review of emerging substances, including synthetic cannabinoids and other novel compounds. This placed mitragynine and 7-Hydroxymitragynine under Wisconsin’s controlled substance framework.

Can Kratom Be Purchased or Shipped Into Wisconsin?

Since Wisconsin’s current laws restrict Kratom-related products, availability of Kratom products is highly limited.

Retail Availability

No licensed retailer in Wisconsin, including any convenience stores, gas stations, or specialty stores — can legally stock Kratom powder, capsules or extracts.

Online Ordering Restrictions

Ordering Kratom for delivery to a Wisconsin address carries the same legal exposure as buying it in person, since Statute 961.14 applies to possession regardless of how the product was obtained.

Why Many Vendors Do Not Ship to Wisconsin?

• Shipping into a Schedule I state creates legal exposure for the sender.
• Package interception at the state line is possible.
• Reputable vendors screen shipping addresses against state-ban lists, including Wisconsin's.

Penalties Related to Kratom Under Wisconsin Law

Beyond restrictions on sales and availability, Wisconsin law also outlines penalties associated with activities involving Kratom-related substances. The table below summarizes the legal classifications and potential consequences under the state’s current framework.

Why Wisconsin's Kratom Law Differs From Federal Policy

Current Federal Status

As of 2026, Kratom itself is not scheduled under the federal Controlled Substances Act. A 2016 DEA proposal to schedule it nationally was withdrawn following public opposition.

State Authority Over Controlled Substances

States can independently classify substances that remain unscheduled at the federal level. Wisconsin did exactly that in 2014, years ahead of most other states that have since taken action.

Why Wisconsin Maintains Its Own Restrictions

Because Wisconsin's ban is a state-level statute, it doesn't depend on federal scheduling to stay in force — and it isn't automatically lifted if federal policy shifts.

How the DEA's 2026 7-OH Action Relates to Wisconsin

What the DEA Announced in July 2026

On July 1, 2026, the DEA filed two Notices of Intent, published in the Federal Register on July 6, 2026, proposing to temporarily place these into Schedule I under 21 U.S.C. § 811(h):

• 7-Hydroxymitragynine (7-OH) above a 0.05% dry-weight threshold (or 1 mg per article in processed forms).
• Three related compounds: mitragynine pseudoindoxyl, MGM-15, and MGM-16.

By statute, the order was set to begin no earlier than August 5, 2026. As of now, the DEA has not yet published a final order, though the 30-day waiting period has passed.

Future Outlook for Wisconsin Kratom Law

National Regulatory Trends

More than a dozen states have now adopted KCPA-style frameworks rather than outright bans, shifting the national conversation toward regulation.

Growth of Kratom Consumer Protection Acts Across the U.S.

Rhode Island became the first state to reverse a full Kratom ban, replacing prohibition with a licensed, age-restricted framework beginning April 1, 2026.

What Could Influence Future Legislative Review in Wisconsin?

Potential factors that could shape future discussions include:

• Legislative proposals introduced at the state level
• Regulatory developments in neighboring states
• Ongoing reviews of controlled substance policies
• Federal developments related to Kratom alkaloids

FAQs

Can I Buy Kratom In Wisconsin?

No. Under Wisconsin's current controlled-substance classification, mitragynine and 7-Hydroxymitragynine are listed as Schedule I substances, so Kratom is not legally available for retail sale in the state.

Can You Get Arrested For Having Kratom In Wisconsin?

Yes. Because Wisconsin classifies mitragynine and 7-Hydroxymitragynine as Schedule I controlled substances, possessing Kratom can result in criminal consequences under state law. The specific penalties depend on the circumstances and applicable Wisconsin statutes.

Has Wisconsin Ever Tried To Legalize Kratom?

Yes. Wisconsin lawmakers have introduced proposals that would have replaced the state's prohibition with a regulated framework, including Assembly Bill 599 in 2017 and Assembly Bill 393 in 2023. However, neither proposal changed Wisconsin's existing controlled-substance classification.

Is It Legal To Fly With Kratom In Wisconsin?

No, not if the Kratom is being carried into or within Wisconsin in violation of the state's controlled-substance law. TSA screening rules and state legality are separate issues: TSA permits many powder-based substances through security, but passing a TSA checkpoint does not make a substance legal under Wisconsin law.

Is Kratom Legal In States Near Wisconsin?

Yes. Wisconsin’s neighboring states take different approaches: Minnesota, Iowa, Michigan, and Illinois currently allow Kratom at the state level, while Indiana bans it statewide. Local restrictions can still apply in some areas.
